Converts a frequency matrix to a weight matrix. Weight matrices are used for probabilistic recognition of transcription factor binding sites.

Parameters in GUI

ParameterDescriptionDefault value
Matrix type (required)Dinucleic matrices are more detailed, while mononucleic one are more useful for small input data sets.Mononucleic
Weight algorithmDifferent weight algorithms uses different functions to build weight matrices. It allows us to get better precision on different data sets. Log-odds, NLG and Match algorithms are sensitive to input matrices with zero values, so some of them may not work on those matrices.Berg and Von Hippel
